Application Information
Instructions for use

Subtrate preparation

Concrete substrate

The surface of the concrete to be prepared shall be sound, clean and uncontaminated.  

This preparation shall be such as to leave a sound exposed concrete surface free from dust, loose particles and any deleterious matter. If the concrete surface is defective or has laitance, it must be cut back to a sound base. Excess laitance deposits are best removed by light mechanical scrabbling, grinding or grit/captive blasting followed by vacuum cleaning to remove dust debris.

Any blowholes, chipping or similar surface imperfections shall be repaired using EPOFINISH, a solvent free epoxy resin repair mortar.  Allow the repair material to harden.
Expansion joints shall be repaired using EPOMORT HS,  a high strength solvent free epoxy mortar.

New concrete or cementitious surfaces should be allowed to cure and have moisture content not exceeding 5%. Old or existing floor should be refurbished mechanically to ensure clear sound substrate.

Priming

Priming is not normally required provided the substrate is sound, clean, free from loose material, grease, laitance, dirt, curing compound etc.

In case of highly porous concrete, it must be treated with PRIMER POXY FF, a solvent-free high performance epoxy primer.

In that case the primer should be applied by brush or roller on to the cleaned surface area (particularly hidden surfaces) at a rate of 5-6 m²/Liter.

The primer should be left to achieve a tack-free condition before applying the top coat. A second coat of primer may be required if the substrate is excessively porous.

Mixing

EPOFLOOR E240 is supplied in two pre-weighed packs (Component A – Base and Component B – Hardener) which are ready for immediate in-situ use. Stir in both components before use.

Transfer the entire content of component B (Hardener) into the component A (Base) can and mix with low speed drill and paddle (200 – 300 rpm) for 2-3 minutes till obtaining a mix with uniform consistency. Scrape the sides and bottom of the can during mixing to ensure homogeneity.

Dilution up tp 8% using Solvente 10 to aid application is permitted.

Application

Apply two coats of EPOFLOOR E240 with a roller, squeegee or airless spray to the primed tack free surface at a consumption rate of 4-5m²/Liter.

Each coat will be a minimum of 200-250 microns thick. The second coat shall be applied after the first coat is completely dry.

The total dry film thickness of the coating shall be a minimum of 400-500 microns.

For anti-slip flooring, silica sand (with suitable size) can be broadcasted directly after the first coat in order to achieve leatherette like finish.
For heavy traffic areas such as drive lanes, ramps, turn areas, or other areas subjected to high abrasive traffic, apply a third coat EPOFLOOR E 240.

Expansion Joints

Expansion joints in the existing substrate must be retained and continued through the EPOFLOOR E 240 topping. COLMEF have a range of joint sealants specifically designed for flooring.

Cleaning

Tools and equipment should be cleaned with SOLVENTE 10 immediately after use. Hardened material should be removed mechanically.
Spillages should be absorbed with sand or sawdust and disposed of in accordance with local regulations.

Recommendations

  • EPOFLOOR E240 should not be applied onto surfaces likely to suffer from rising dampness or relative humidity >70%.
  • EPOFLOOR E240 should not be applied at temperature below +5°C.
  • EPOFLOOR E240 should not be applied at asphalt floors or PVC tiles.
  • EPOFLOOR E240 should be applied internally. If used exteriors it is strongly recommended to cover with one or two coats of EPOFLOOR UV2.

Chemical Resistance

Fully cured EPOFLOOR E240 samples have been tested in a wide range of aggressive chemicals commonly found in industrial environments. Tests were performed in accordance to ASTM D543 standards over 7 days at +25°C.
